The assessment of physicians' and senior medical students’ knowledge in the field of communityacquired pneumonia: preliminary results of the KNOCAP-II project (2017-2019)

Внебольничная пневмония (ВП) относится к одной из самых актуальных проблем современной медицины. На сегодняшний день ВП занимает 4 место в структуре смертности (после сердечно-сосудистых, цереброваскулярных заболеваний и злокачественных новообразований) и 1 место среди всех смертей от инфекционных заболеваний. Цель – оценка уровня знаний врачей терапевтического профиля и студентов старших курсов медицинских вузов в вопросах ведения пациентов с ВП. В рамках многоцентрового исследования KNOCAP (полное название проекта – «The assessment of physician and students’ knowledge of community-acquired pneumonia basics») представлены результаты анонимного проспективного опроса по оценке знаний и предпочтений врачей терапевтического профиля и студентов старших медицинских курсов в вопросах ведения пациентов с ВП. По итогам первого периода проекта (2017-2019 гг.) получены и проанализированы результаты анкетирования 588 врачей терапевтического профиля и 394 студентов-медиков из 17 центров России, Украины и Кыргызстана. За основу взят метод анонимного анкетирования, для чего была разработана оригинальная анкета на основании актуальных клинических рекомендаций. Наибольшие сложности вызвали следующие вопросы: сроки проведения повторного рентгенологического исследования при положительной динамике лечения, выбор основного диагностического признака при ведении пациента с ВП, указать типовые ошибки фармакотерапии ВП и выбор стартовой антимикробной терапии у пациентов с факторами риска и без них. В целом исследование показало значимое несоответствие знаний в вопросах ведения пациентов с ВП актуальным клиническим рекомендациям 2010 г. и проектом новых клинических рекомендаций 2018-2019 гг. В настоящее время существует необходимость в повышении уровня знаний и совершенствовании профессиональной деятельности врачей терапевтического профиля и студентов старших медицинских курсов, так как проведенный многоцентровой срез знаний и предпочтений специалистов во многих вопросах выявил их недостаточный уровень для корректного ведения пациентов с ВП. Community-acquired pneumonia (CAP) is one of the most relevant problems of modern medicine. Today, CAP takes 4th place in the structure of mortality (after cardiovascular, cerebrovascular diseases and malignant neoplasms) and 1st place among all deaths from infectious diseases. The aim of the study is to assess the level of general physician’ and senior medical students’ basic knowledge in CAP treatment. The article represents the results of anonymous prospective surveys within the framework of the second stage of KNOCAP multi-centered research project (full name of the project «The assessment of physician’ and students’ knowledge of community-acquired pneumonia basics») aimed at accessing the knowledge and preferences of doctors and students on the fundamental issues in diagnosis and treatment of community-acquired pneumonia. The survey conducted in 2017-2019 involved 588 physicians and 394 students from seventeen Russian, Kyrgyzstan and Ukrainian centers. The method of anonymous questioning was used in this study, for which an original questionnaire was developed on the basis of current clinical recommendations. The following fundamental questions caused the greatest difficulties in the respondents: terms for a repeated X-ray examination in positive dynamics of CAP treatment, the choice of main diagnostic criteria of CAP, the choice of the typical mistakes of CAP treatment, the choice of the initial antimicrobial therapy. In general, the respondents’ knowledge in CAP patients’ management deviates significantly from the current clinical guidelines, as of 2010, and from the new clinical guidelines draft, 2018-2019. Currently, there is a need to increase the level of knowledge and improve the professional activities of therapists and senior medical students, as a multicenter section of the knowledge and preferences of specialists in many issues revealed their insufficient level for the correct management of patients with CAP

ANALYSIS OF STATISTICAL INDICATORS OF INDUSTRIAL RISKS FOR CERTAIN TYPES OF ECONOMIC ACTIVITY

В работе рассматривается аварийность на промышленных производствен-ных объектах. Исследованы статистические данные за период 2010 – 2018 гг. по следующим видам экономической деятельности: добыча полезных иско-паемых, обрабатывающее производство, производство и распределение электроэнергии, газа и воды. Рассчитаны относительные показатели количе-ства пострадавших на производстве к среднесписочной численности работа-ющих и суммы затрат на охрану труда к объему производства в динамике за исследуемый период. We have investigated accidents at industrial production facilities. We reviewed statistical data for the period 2010-2018 for the following economic activities: mining, manufacturing, production and distri-bution of electricity, gas and water. We calculated the relative indicators of the number of victims at work to the average number of employees and the amount of labor protection costs to the volume of production in dynamics for the study period

Visualizing Lipid Raft Dynamics and Early Signaling Events during Antigen Receptor-mediated B-Lymphocyte Activation

Recent biochemical evidence indicates that an early event in signal transduction by the B-cell antigen receptor (BCR) is its translocation to specialized membrane subdomains known as lipid rafts. We have taken a microscopic approach to image lipid rafts and early events associated with BCR signal transduction. Lipid rafts were visualized on primary splenic B lymphocytes from wild-type or anti-hen egg lysozyme BCR transgenic mice, and on a mature mouse B-cell line Bal 17 by using fluorescent conjugates of cholera toxin B subunit or a Lyn-based chimeric protein, which targets green fluorescent protein to the lipid raft compartment. Time-lapse imaging of B cells stimulated via the BCR with the antigen hen egg lysozyme, or surrogate for antigen anti-IgM, demonstrated that lipid rafts are highly dynamic entities, which move laterally on the surface of these cells and coalesce into large regions. These regions of aggregated lipid rafts colocalized with the BCR and tyrosine-phosphorylated proteins. Microscopic imaging of live B cells also revealed an inducible colocalization of lipid rafts with the tyrosine kinase Syk and the receptor tyrosine phosphatase CD45. These two proteins play indispensable roles in BCR-mediated signaling but are not detectable in biochemically purified lipid raft fractions. Strikingly, BCR stimulation also induced the formation of long, thread-like filopodial projections, similar to previously described structures called cytonemes. These B-cell cytonemes are rich in lipid rafts and actin filaments, suggesting that they might play a role in long-range communication and/or transportation of signaling molecules during an immune response. These results provide a window into the morphological and molecular organization of the B-cell membrane during the early phase of BCR signaling

Fourth report on chicken genes and chromosomes 2022

The chicken continues to hold its position as a leading model organism within many areas of research, as well as a being major source of protein for human consumption. The First Report on Chicken Genes and Chromosomes [Schmid et al., 2000], which was published in 2000, was the brainchild of the late, and sadly missed, Prof Michael Schmid of the University of Würzburg. It was a publication bringing together updates on the latest research and resources in chicken genomics and cytogenetics. The success of this First report led to the subsequent publication of the Second [Schmid et al., 2005] and Third [Schmid et al., 2015] reports proving popular references for the research community. It is now our pleasure to be able to introduce publication of the Fourth report. Being seven years since the last report, this publication captures the many advances that have taken place during that time. This includes presentation of the detailed genomic resources that are now available, largely due to increasing capabilities of sequencing technologies and which herald the pangenomic age, allowing for a much richer and more complete knowledge of the avian genome. Ongoing cytogenetic work also allows for examination of chromosomes, specific elements within chromosomes and the evolutionary history and comparison of karyotypes. We also examine chicken research efforts with a much more ‘global’ outlook with a greater impact on food security and the impact of climate change, and highlight the efforts of international consortia, such as the Chicken Diversity Consortium. We dedicate this Report to Michael
